Is it possible to have a breast uplift, existing implants replaced with smaller versions and a tummy tuck done at the same time?

Dear Enthusiastic3892 thank you for your question!
Combining breast and body contour procedures is sometimes referred to as a mommy makeover. It is possible to do both procedures in a single stage safely as long as they are performed by experienced surgeons in approved facilities.
Combining procedures has the advantage of reducing the number of anesthetic periods, as well as limiting expenses associated to separate surgical episodes.

These procedures are frequently done together and are commonly referred to as a "mommy makeover."
The length of time under anesthesia may slightly increase your risks for blood clots in your legs. Seek a consultation with a board certified plastic surgeon. He or she can do a risk assessment to help determine the safety of combining the procedures.

It is possible to combine these procedures however it depends on your surgeon’s opinion, based on your health, their experience and what your surgery involves. An assessment would need to be performed by your surgeon in order to determine whether combining these would be safe for you.
